I’ve said it before and I will say it again…
Keep 👏 Your 👏 Rainbowfish 👏 In 👏 Proper 👏 Schools
Why? Because keeping them in groups of 6 or more not only drastically reduces their stress, but it also triggers their natural displaying behaviors—which is exactly how you get those brilliant, flashing blue and yellow colors you wanted in the first place!
And if you are having a hard time doing this? Here’s a helping hand!
If your Boesemanis are looking pale or acting skittish, take a look at their environment and diet. Make sure they have at least a 55-gallon tank with plenty of horizontal space to sprint back and forth, and upgrade their meals to a high-protein mix of frozen bloodworms and brine shrimp. You will see their true colors wake up almost overnight.
So remember, don’t just buy one or two and toss them into a cramped community tank. Give them the crew and the swimming room they need to thrive!
